“A top Hamas official said the Palestinian militant group is losing faith in the United States’ ability to mediate a cease-fire in Gaza ahead of a new round of talks scheduled for this week amid mounting pressure to bring an end to the 10-month-old war with Israel. Osama Hamdan told The Associated Press in an interview Tuesday that Hamas will only participate if the talks focus on implementing a proposal detailed by U.S. President Joe Biden in May and endorsed internationally. The U.S. referred to it as an Israeli proposal and Hamas agreed to it in principle, but Israel said Biden’s speech was not entirely consistent with the proposal itself. Both sides later proposed changes, leading each to accuse the other of obstructing a deal. Hamas is especially resistant to Israel’s demand that it maintain a lasting military presence in two strategic areas of Gaza after any cease-fire, conditions only made public in recent weeks.”
